The size of the Smart Query Filter (BF.ptn) is proportional to the file size of the Smart Scan Pattern, which has been growing rapidly due to increased threats in recent months. As a result, the Smart Query Filter has to update and redeploy itself to Smart Scan clients. The size of the update is approximately 7MB to 11 MB. This is required by all Smart Scan clients.

This affects the users of Smart Scan method of scanning for OfficeScan 10, 10.5, 10.6, and Worry-Free Business Security (WFBS) 6.0 and 7.0 clients.

Clients using conventional pattern are not affected. This article applies to WFBS Advanced only.

For OfficeScan, WFBS and Stand-Alone Smart Scan Server 2.0, a built-in throttling function resolves this network capacity issue. This function is automatically enabled if the product detects that the BF.ptn size increased.

For OfficeScan 10.0, WFBS 6.0, and Stand-Alone Smart Scan Server 1.0, apply patches with bandwidth throttling feature limiting the number of OfficeScan/WFBS clients that are able to download 7 MB file at a given time. By default, the patches allow five (5) clients to download the 7 MB file. Afterwards, the patches let the clients wait for 15 seconds before allowing the next batch of clients to download the 7 MB file.
